Nothing in RFC7934 says that any part of DHCPv6 is NOT RECOMMENDED
(or SHOULD NOT be used, which is the same thing). Specifically,
there is no normative statement whatever about IA_NA or IA_TA.


But it does make a normative recommendation against their exclusive use.

Specifically, it says it is RECOMMENDED to give hosts the ability to form
new addresses without explicit requests to the network. That recommendation
cannot be met on a network that *only* provides addresses via IA_NA / IA_TA.

So while it makes no normative recommendation about IA_NA / IA_TA
themselves, it does make a normative recommendation against running a
network that uses IA_NA / IA_TA as its only address assignment mechanism.
